This booster provides nitrogen to purge the seals of a large centrifugal compressor. Both machines are owned by a petrochemical company in the Persian gulf area. Due to the extreme working conditions with high temperature and sand storms, but also to further reduce the noise level, a removable acoustic enclosure was provided. The whole enclosure is cooled to maintain stable ambient conditions. The compressor has been tested in our ABC facilities, witnessed by the client. This compressor was packaged in the Netherlands.
